Are we Iranian going to see a more convulsive Presidential Election in Iran ?

The atmosphere among Iranian Society is already began to change with Hashemi Rafsanjani ( Candidate Close to reformists & Green movement ) and Esfandiar Mashaei ( Current Government Candidate ) nominating themselves today. Although the regime will not change if Rafsanjani's elected as president but the atmosphere is going towards convulsion and the nominees has already started speaking in a way it looks like threatening each others.
Will their be a peaceful or calm election days ahead ? There are fears that radical conservatives, those of "Jebhe Paydari" ( Resistance Front) " including Ahmadinejad & Mashaei's supporters may disrupt the election process .
For example:

Hassan Rohani a candidate close to reformists : "If some people will continue to use the word " Fetneh " ( Sedition ) , i have no choice but to speak about issues that i feel isn't time to speak about it. unfortunately not only the security condition of the country must changed , and at present the security condition of the university's must also be change . "

Many believe Ahmadinejad's continued travels to the provinces and city's has an agenda for the coming election and a support for Mashaei.
Clashes were reported between Mashaei's and Qadiri Abyaneh's ( another candidate ) supporters at the election headquarter.
