Allen is currently the frontrunner for the GOP nomination. This Senator from Virginia brings a good mix of legislative and executive experience to the ticket, but I see him as a bit of a lightweight. Certainly not the worse person who could win the nomination, but I see him more as a consensus candidate between the moderate and conservative wings of the party. The Republicans would benefit more running a more moderate candidate like John McCain who could beat Democrats in states like Pennsylvania, Illinois and California, while still holding the South. Plus it would benefit the Republicans to move away from the Bush Administration's policies, which aren't aging well.
