Monday is the filing deadline for candidates who want to run in New Jersey's June primary.
Political analysts expect a battle to get the Republican nomination for Governor.
Lt. Governor Kim Guadagno has won the endorsement of GOP organizations in 10 counties to get favorable placement on the primary ballot and Assemblyman Jack Ciattarelli will have that coveted designation in 7 counties.
Montclair State University political science professor Brigid Harrison believes Guadagno has the upper hand now, but Governor Christie's low approval ratings could affect the outcome.
"Even among Republicans you do see some dissatisfaction with the Christie administration and if they hold this against her, she could be in for a bit of a trouble."
Guadagno now has more name recognition among voters than Ciattarrelli.
Rider University political science professor Ben Dworkin says that advantage could fade.
"He hasn't started spending money in a serious way on television advertising. I'm sure that will happen as we head into late April and May, and as that happens his name recognition will dramatically increase."
