UNDATED (WSAU-Wheeler News) A national poll gives Governor Scott Walker a slight lead over Jeb Bush among the potential Republican presidential candidates. However, Quinnipiac University of Connecticut has Walker losing to Democrat Hillary Clinton 48-to-39 percent in a general election match-up that’s 20 months away.

Among Republican voters, Walker has the lead with 18-percent to 16-percent for ex-Florida Governor Bush. The next two Republicans are well down the list, with Chris Christie and Mike Huckabee getting eight-percent each. None of the Republicans would beat Clinton at this point. Bush comes the closest at 45-42. If Walker doesn’t run, Bush would lead physician Ben Carson at 18-to-10 percent. If Bush doesn’t run, Walker would have a 20-to-10 percent lead over Christie.

Clinton is the Democrats’ clear choice. 56-percent in the Quinnipiac poll support her, with Massachusetts Senator Elizabeth Warren second at 14-percent. If Clinton doesn’t run, Vice President Joe Biden gets the edge with 35-percent to 25 for Warren.

59-percent in the Quinnipiac poll want the next president to change the direction of the country, while only 30-percent want to see Barack Obama’s policies continue. Almost 13-hundred registered voters were polled from last Thursday through Monday.

The overall margin of error is 2.7-percent — and it’s just over 4-percent either way for the separate Republican and Democratic voters surveyed.
