CNN reports that Gov. Sarah Palin (R-AK) is set to announce soon that she will not run for a second term as Governor in 2010.

There are any number of reasons she might not be running again -- but it's worth pointing out that Gov. Tim Pawlenty (R-MN) also recently announced his retirement, which most people see as a step towards a potential run for President in 2012.

And given the huge distances involved, it's hard to travel all around the Lower 48 while also being an actual Governor of Alaska. Palin had to essentially leave the state during the two months that she ran for Vice President back in 2008.

Could we be seeing a Palin/Bachmann ticket in 2012?
