CLEVELAND, Ohio - A new poll released Tuesday shows what others in recent weeks have: the race for governor between Republican Mike DeWine and Democrat Richard Cordray is close and Democratic U.S. Sen. Sherrod Brown has a comfortable double-digit lead over Republican U.S. Rep. Jim Renacci in the race for Senate.

The poll increases the sample from recent weeks and showed a statistical tie in the race for governor. And while the poll was the best showing for Renacci in any public survey, Brown still led handily.

The poll from NBC News and Marist College is fairly in line with recent polls from Quinnipiac University, Suffolk University and Fallon Research.

The poll was conducted June 17-22 of 778 registered voters and has a margin of error of plus-or-minus 4.4 percentage points. Marist conducted the poll via live landline and cell phone interviews.

DeWine vs. Cordray

Republican Attorney General Mike DeWine had a slight lead on Democratic former federal watchdog Richard Cordray in Tuesday's poll, with 46 percent saying they supported DeWine and 42 percent saying they supported Cordray. Eleven percent were undecided.

Almost half of respondents - 48 percent - said they were firmly supporting their candidate, including 52 percent of Cordray supporters and 44 percent of DeWine supporters.

Brown vs. Renacci

The results from the Marist poll were slightly better for Renacci, but show he still has a long way to go if he ever hopes to topple Brown.

Brown led Renacci by 13 points with 51 percent supporting Brown and 38 percent supporting Renacci. The 13-point differential is Renacci's closest in any public polling thus far.

Brown also had stronger supporters - 55 percent said they strongly supported the candidate compared with only 43 percent of Renacci's supporters saying they strongly supported the congressman.

Compared to others

The NBC/Marist poll compares well with others in recent weeks. A Quinnipiac poll from June showed a statistical tie in the governor's race, though Cordray led and DeWine was at 40 percent. The same poll showed Renacci at only 34 percent support. Cordray and Brown had the same amount of support in both the Marist and Quinnipiac polls.

A Suffolk University/Cincinnati Enquirer poll showed Democrats in a better position. That poll had Cordray leading by 7 points with 46 percent. Brown led Renacci by 16 points at 53 percent.
