Omnibus political web site RealClear Politics has the news that a Mitt Romney Super PAC is doing an 8-state, $1.5 million ad buy in advance of Super Tuesday on March 6. (Super PACs are non-profits that don't have to disclose donors and can accept unlimited, direct donations from corporations and unions as a result of the Citizens' United decision)

However, Washington, which holds its caucuses on March 3, is not on their agenda. RCP reports:

The group is also declining for the time being to advertise in Washington state (which holds caucuses March 3) and in Alaska, Idaho and North Dakota -- the three Super Tuesday caucus states where turnout is likely to be small and where Rick Santorum could do particularly well.

In an implicit acknowledgment that the battle for the Republican nomination is likely to go beyond Super Tuesday, Restore Our Future has also purchased broadcast TV spots this week in two Southern states that will hold their primaries on March 13: Alabama ($84,000) and Mississippi ($68,000).

Washington's GOP caucuses will choose delegates to the county Republican conventions, which will pick delegates to the state convention—where Republicans will finalize how many delegates each GOP contender gets at the national GOP convention. Conservative blog Sound Politics explains the process here adding: "And if you're a Democrat, go play ball that day, or something. It's not like you don't know who your candidate is going to be."
