Dem polls show shutdown hurt GOP chances in Senate races

In all of the tested states, voters oppose the government shutdown by lopsided margins, a sign that the shutdown may be damaging Republicans' electoral chances.

Partisan polls should always be read with some amount of skepticism, and the way the question is worded seems to place the blame completely on the GOP, which may not be how voters view the situation and could inflate Democrats' standing in some of the later ballot tests. The shutdown appears to be nearing its conclusion, as well, and it's unclear how much this debate will impact an election that's more than a year away.

But nonpartisan national polling has found that voters blame the GOP much more for the shutdown than Democrats, and these results indicate that the ongoing shutdown may be badly hurting Republicans' hopes of winning a majority in the Senate next year.

"These polls make it clear that across the country, whether a state voted for Obama by 10 points or voted for Romney by 20, voters are extremely angry about the government shutdown. And it’s going to make Republican hopes of taking back the Senate next year that much harder," writes PPP pollster Tom Jensen in the memo.
