(CNN) - Pictures can speak a thousand words.
At least that's what former Florida House Speaker Marco Rubio hopes.
The conservative Republican battling Gov. Charlie Crist for the GOP Senate nomination in that state has unveiled a new Web site showing a single full-page image of Crist with President Obama at a rally for the president's stimulus package last February.
"Get the picture?" text under the image reads. "Donate now to stand up for conservative principles."
Crist was one of only a handful of Republican governors to extend some support to the president's $787 billion stimulus package - a move that rankled some conservatives in his home state and across the country.
Since the Senate primary race began last May, Rubio has become the favorite of conservative Republicans while national party leaders are openly supporting Crist. Recent polls suggest Crist holds a 15 point lead over Rubio, a margin that is down from more than 30 points last summer.
The picture of Crist and Obama could resonate with conservatives in a similar way an image of Connecticut Sen. Joe Lieberman embracing President Bush resonated with liberal Democrats in 2006. Lieberman lost his Democratic primary to a liberal challenger that year, though won the general election as an independent.
