WASHINGTON (AP) — A former Maryland governor who is considering running for president says he's not worried about any presumption that Hillary Rodham Clinton is the front-runner for the Democratic nomination

Martin O'Malley says "every year, there is the inevitable front-runner." He says he'll decide this spring whether to run and that he expects "a robust conversation" within the party.

Speaking Thursday on MSNBC, O'Malley refused to be drawn into a substantive discussion of Clinton's email controversy.

He says that even if there were a uniform email policy across all levels of government, "none of that would make a hill of difference" to people struggling to pay their bills.

O'Malley says the email question is "not the issue that's going to restore our economy."
