If you're a voter in an upcoming primary state, chances are you'll see a lot of pro- Romney super PAC ads.

On Wednesday, the Romney-backing super PAC Restore Our Future reported big purchases of TV time in Tuesday's primary states of Mississippi and Alabama, as well as Illinois and Louisiana, which hold primaries on March 20 and March 24, respectively.

It was once unthinkable, according to conventional wisdom, that the Republican primary would stay competitive long enough for a heated battle over the heavily Democratic Illinois. However, Restore Our Future is spending more money there than in any other upcoming state-likely because ads in the Chicago media market are expensive.

Restore Our Future reported new spending of $901,438 in Illinois, $425,165 in Louisiana $680, 385 in Alabama, and $581,183 in Mississippi.

Below, see which ads are airing where, according to a Restore Our Future spokeswoman.
