Rubio, as well as another Romney surrogate in Congress, Rep. Mary Bono Mack (R-Calif.), urged Twitter followers to download the app on Tuesday in order to be the “first” to hear Romney’s VP choice. Because their tweets were nearly identical, it’s likely that they are following the Romney campaign’s lead in pushing the app to supporters.

But it would not be the first time that the campaign used Twitter to tease supporters about Romney’s choice.

Last Friday, Beth Myers, the Romney aide in charge of the VP vetting process, tweeted a list of names to follow on Twitter that was identical to those most likely on the short list of candidates.
