WASHINGTON (AP) -- The top two contenders for the Republican presidential nomination are accusing each other of benefiting from the support of crossover Democratic voters in states that allow anyone to participate in a party primary.
And both are correct.
Mitt Romney and Rick Santorum have each worked to woo independent voters and conservative Democrats during campaign appearances. While it may be distasteful to their hard-core GOP supporters, it's an acknowledgement of the kind of crossover appeal that any GOP nominee will need in November if he's to beat President Barack Obama.
It also creates a tricky rhetorical tightrope for the candidates: making a pitch to non-Republican voters while finding fault when an opponent does the same thing.
