(CNN) - Hillary Clinton’s campaign is pointing to her victories in the Republican-heavy states of Tennessee, Arkansas and Oklahoma as proof she can win in areas far from the coasts. “With these first two victories, Hillary Clinton has demonstrated that she can compete and win in red states,” read a Tuesday night campaign statement.

The Obama campaign has pointed to its major endorsement haul from Democratic elected officials in majority-Republican states.

Sen. Clinton spent many years as Arkansas’ first lady. Tennessee allows Democrats, Republicans and Independents to vote in its Democratic primary, but according to CNN’s exit poll, Obama actually scored marginally higher than Clinton among independents who chose to vote in the Tennessee primary (CNN did not poll Republican voters in the Democratic primary).

Oklahoma, for its part, has a “closed” Democratic primary, meaning that only registered Democrats can vote; so there’s no way to know what choice Oklahoma’s registered Republicans would make.
