WASHINGTON — Democrats are finding that their path to keeping control of the U.S. Senate this year is getting bumpier.
At least four states where Democrats hold Senate seats that once were seen as fairly safe are now considered in play: Michigan, Iowa, Colorado and New Hampshire.
They join seven states with Democratic incumbents where analysts see decent bets for Republican pickups: Alaska, Arkansas, Louisiana, Montana, North Carolina, South Dakota and West Virginia. Republican presidential nominee Mitt Romney carried all seven in 2012.
The new four are now battlegrounds for the same reasons that plague Democrats elsewhere. The Affordable Care Act is detested in many circles. Anyone associated with Washington is often toxic. And popular Republicans who are running for other offices are often on the ballot.
The common thread is that theres a Democrat in the White House whos not that popular, said Kyle Kondik, the managing editor of Sabatos Crystal Ball, a nonpartisan research group at the University of Virginia. It wouldnt be surprising if any of those states went Republican.
Republicans also appear more motivated. Theres a sense that a possible takeover of the Senate is real, and that will give a boost to the Republicans ability to thwart the presidents agenda said Chris Budzisz, the director of the Iowa-based Loras College Poll. He was speaking of Iowans, but the perception holds more broadly.
Republicans need a net gain of six seats for a Senate majority. Democrats are defending 21 seats, Republicans 15.
Only two Republican-held seats are considered vulnerable. In Kentucky, if Senate Republican leader Mitch McConnell wins a primary next month as expected, he'll be challenged by Secretary of State Alison Lundergan Grimes, a Democrat.
In Georgia, where Sen. Saxby Chambliss, R-Ga., is retiring, a multi-candidate Republican field is seeking the nomination. The winner is expected to face well-funded Democrat Michelle Nunn.
Heres the outlook in the four new tossup Democratic-held states:
Sen. Carl Levin, D-Mich., is retiring, and Rep. Gary Peters, D-Mich., is trying to take his place.
Republican former Secretary of State Terri Lynn Land, whos also seeking the seat, led Peters by 6 percentage points earlier this month in a poll by Mitchell Research, a Michigan-based firm.
Democrats dont have much to be excited about, said Bill Ballenger, the editor and publisher of the newsletter Inside Michigan Politics, and Republicans are pretty cranked up. Democrats point to an April 3-6 Public Policy Polling survey that found Peters slightly ahead.
Peters barely lost a race for attorney general in 2002. Land has run twice statewide and won handily. Michigan voters are used to gravitas from their senators Levin, incumbent Debbie Stabenow, Donald Riegle, Arthur Vandenberg, Philip Hart and so far Gary Peters is not cut from that same cloth, said Ballenger.
Sen. Jeanne Shaheen, a Democrat, has a long history of winning statewide races, first as a campaign strategist and then as governor and senator.
And few thought Republican former Massachusetts U.S. Sen. Scott Brown would pose much of a challenge. Brown is now in the race, and a Granite State poll taken April 1-9 showed him 6 percentage points behind.
One of Shaheens problems: Those who have moved into the state from Massachusetts about one-fourth of those surveyed preferred Brown by 13 points.
Justin Barasky, a spokesman for the Democratic Senatorial Campaign Committee, had a different view of the numbers.
The only thing we know is hes losing, and his favorable numbers are underwater, he said. Brown was viewed unfavorably by 39 percent, while 29 see him favorably.
New Hampshire has been a swing state in recent years. Obama won it with 52 percent in 2012, and its congressional voting has largely mirrored the nations. It elected Democrats to its two House of Representatives seats in 2006, when the party won control of the chamber. Four years later, when Republicans regained control, the state elected two Republicans. In 2012, it ousted both and elected Democrats.
Sen. Tom Harkin, a Democrat, is retiring.
It could very well become an opportunity for Republicans, said Budzisz.
One reason is the strength of Gov. Terry Branstad, a highly popular Republican whos running again.
Two other factors might determine the Senate winner: the eventual Republican nominee, who'll be chosen later this year, and the campaign effectiveness of Democrat Bruce Braley, a four-term congressman.
Braley stumbled earlier this year when he said Sen. Charles Grassley, a Republican, was a farmer from Iowa who never went to law school, never practiced law. Republicans complained that Braley was insulting farmers.
Personality and personal campaigning matter in Iowa. For 30 years, Grassley and Harkin have been at opposite ends of the political spectrum but have won because they know how to relate to state residents, said Budzisz., and they often vote in similar ways on meat and potatoes issues, notably agriculture.
Incumbent Mark Udall, a Democrat, had looked fairly safe until Rep. Cory Gardner, a popular Republican, entered the race in late February.
Its definitely a race, said Denver-based consultant Floyd Ciruli. Udalls ties to Obama, and his vote for the health-care plan, hurt.
Obama won the state in 2012 with 51.4 percent of the vote, but this year the enthusiasm is on the Republican side, where partisans are eager to send a message to incumbents.
People think Washington is the pits, Ciruli said.
Democrats will try to paint Gardner as an out-of-touch conservative. Gardner scored an 84 rating from the American Conservative Union last year, slightly above Republicans 76.48 percent average. Hes far out of step with mainstream Colorado voters, said Barasky.
Could be, but Ciruli had a different take. Its a lousy year to be a Democrat, he said, even in a swing state.
