At least seven Senate incumbents struggling below halfway mark in polls

At least seven Senate incumbents struggling below halfway mark in polls

At least seven Senate incumbents in competitive races are struggling to reach the 50 percent mark in the polls.

The group includes both Democrats and Republicans — showing incumbents in both parties are subject to voters’ wrath.

Russ Feingold (D-Wis.) can’t crack 46 percent, while Blanche Lincoln (D-Ark.) appears to be in the worst shape. Lincoln’s highest polling number all summer was 35 percent in a mid-July Reuters/Ipsos survey.

Labor Day marks the start of the final stretch of the campaign season. Any incumbent polling below 50 percent at that point is considered in serious trouble.

But Ross Baker, a political scientist at Rutgers University, said the incumbents still have time to recover strength.

“Obviously, below 50 percent is a firebell in the night for any incumbent — but it’s not Labor Day yet,” Baker said. “Looking at it race by race, even though there a large number of them, some of those sub-50s will recover nicely.”

Tom Jensen, director of Public Policy Polling (PPP), which conducts a wide variety of national and state-specific congressional polls, says the high number of endangered incumbents might be the most he’s ever seen.

“There’s definitely a high number, and almost an unprecedented level of discontent with politicians,” Jensen said. “It seems the economic recession has created a recession in political approval ratings. Very few people have been unable to buck that trend.”

Specifically, Jensen said PPP has conducted polls on about 80 Senate and gubernatorial races this year, with fewer than 10 percent of candidates receiving ratings above 50 percent.

“What we're also finding right now is that independent voters are down on everyone,” Jensen said. “Almost no senator has positives with them. Senators are also running into resistance in their own party. People from the opposing party dislike them more strongly, but often their own bases are not as happy with them either.”

The low ratings do not necessarily translate into trouble. Vitter’s numbers are still high enough to hold a double-digit lead over Democrat Charlie Melancon. Boxer, Reid, Murray and Feingold hold single-point leads.

Both Baker and Jensen said the candidates who are faring the best are those who attack early and paint their opponents as a worse alternative. That strategy helped Sen. John McCainJohn McCainUS democracy is in crisis. Trump voters must help us get past it. The rise of Carlson, and the fall of Van Susteren Booker to vote against Tillerson MORE (R-Ariz.) define former Rep. J.D. Hayworth (R-Ariz.) as unsuitable for office, Baker noted, while Sen. Lisa Murkowski (R-Alaska) suffered her likely primary loss because she was complacent about Republican primary rival Joe Miller.

“Being below 50 percent does signify danger, but not necessarily a calamity,” Baker said. “The more experienced and savvy incumbents have developed a way of fending off attacks.

“Reid is a good example. He was ready to go with defining and framing ads to portray [GOP challenger Sharron] Angle as far out of the mainstream, and she’s basically spent the whole campaign disavowing things she’s said in the past, on the record.

“So this is much stronger of an anti-incumbent mood than usual for a mid-term election, both in the severity and the duration. There will be a lot of casualties. But it’s also a test of incumbents.”

Jensen said it is likely too late for any of the sub-50 percent incumbents to crack that threshold. Yet he agreed with Baker that it might be enough to simply make their opponents seem like a worse choice.

“Clearly, Reid has had some success with that in Nevada,” Jensen said. “I don’t think any of them are going to be liked any more, but it’s about the lesser of two evils. If the 2008 election was about hope, 2010 seems to be about making people hate your opponent more than they hate you.”
