Mitt Romney is still having trouble winning over the conservative crowd, according to more preliminary exit polls from Florida.

Four in 10 voters describe Romney as "not conservative enough," while only two in 10 describe Newt Gingrich that way, reports ABC News's Gary Langer, of Langer Research Associates.

The same number of voters are apparently still looking for another candidate. Four in 10 "say they'd like to see someone else running for the nomination," Langer reports. Two-thirds of voters say they'd be satisfied with Romney as the nominee, and about half say that about Gingrich and Rick Santorum.
