A new poll from Iowa has Michele Bachmann ahead of Mitt Romney; looks like her signature on that incredibly insane “marriage vow” boosted her popularity in the Iowa Tea Party base.

The conservative congresswoman finished first among the GOP presidential candidates in a poll released today by The Iowa Republican, a blog which bill itself as News for Republicans, by Republicans. Bachmann received support from 25 percent of likely Iowa caucus-goers. Former Massachusetts Gov. Mitt Romney received 21 percent, putting Bachmann’s lead within the poll’s 4.4 percent margin of error.

Bachmann officially launched her presidential campaign from her hometown of Waterloo, Iowa, and her first campaign ad touts her Iowa roots. She was also the first candidate to sign a “values” pledge created by Family Leader CEO Bob Vander Plaats, an influential Iowa Christian.
