Senator and Former First Lady Hillary Clinton (D) leads actor and former U.S. Senator Fred Thompson (R) by three percentage points in the latest Rasmussen Reports national telephone survey. Clinton attracts 47% while Thompson earns support from 44% (see crosstabs).

That’s a four-point improvement for Clinton from a month ago. In our April survey of this match-up, the gruff-voiced star of "Law and Order" had a one-point edge, 44% to 43%.

Clinton also enjoys a three-point lead over former Massachusetts Governor Mitt Romney (47% to 44%). That's an improvement for Romney who trailed Clinton by nine in March. Romney has proven to be a surprisingly effective fundraiser and is getting better known to voters these days. But only 37% view him favorably, while 38% view him unfavorably.

Fred Thompson has similar favorables to Romney—39%. However, a large number of potential voters don’t yet venture an opinion on him. Just 27% view the TV star unfavorably at this time. NBC recently ordered up another season of "Law and Order," but creator Dick Wolf says he hasn't been told yet whether Senator Thompson will continue to star in it.

In the tightening race for the GOP presidential nomination, fourth-ranked Romney continues to trail Thompson, who jumped into third place as soon as Rasmussen Reports started adding his name to our surveys of the primary contest.

Hillary Clinton's favorable rating remains more or less balanced by her unfavorable rating: 50% view her favorably, 49% unfavorably. Many more have a Very Unfavorable (35%) than Very Favorable (23%) view. Her favorable ratings have been pretty stable over the last several months.
