Pollster Scott Rasmussen ‘s most recent numbers in the Republican prirmary for the Florida Senate seat show a 43%-43% tie among likely primary voters between Governor Charlie Crist and former House Speaker Marco Rubio. This represents a huge change from previous Rasmussen polls on this race: Crist led 53%-31% in August and 49%-35% in October.

Rubio’s very favorable ratings have shot up sharply in the intervening four months. Crist is a Republican who has taken un-conservative stands on issues from hurricane insurance to the Democrats’ February stimulus package, which he supported and in behalf of which he made a joint appearance with Barack Obama.
