It appears Mitt Romney has built some momentum coming off of Tuesday's twin wins in Michigan and Arizona. The former governor has again seized substantial leads in two polls of national Republicans. Gallup:
A new national poll shows Mitt Romney increasing his lead to 11 percentage points over top challenger Rick Santorum as the Republican presidential campaign intensified ahead of Super Tuesday's crucial votes in 10 states. The latest Gallup tracking poll showed Romney -- boosted by an outright win this week in Arizona and a slim win in his home state of Michigan -- with 35 percent support, to 24 percent for Santorum. The Gallup survey represents a daily snapshot of a candidate's standing.
