I am not sure how you come to this conclusion. Is it something he said, or history of his actions, or a general attitude against the Republican party, or something else?
Romney and the Republican party in general want to make the Patriot Act "stronger" for example (watch the Republican debates from last fall. The only one arguing against it was Ron Paul. The others were all towards "more security", disregarding any civil liberties that might step on).
They would like a war with Iran, and we all know things get even worse during war time, when it comes to to civil liberties. And last but not least, Romney can not be trusted, so it's irrelevant even if he says he is pro-Internet freedom (btw he said recently he wants to ban porn or something like that) or pro-civil liberties.
While you may be able to find attribution of that to some fringe elements of the Republican party, I have not heard Romney or Ryan say anything even close. In fact, they seem to be far more process oriented than the current administration that continues to try to find ways around government process (avoiding votes, expansion of executive orders, use of conference, recess appointments, etc).
There is some evidence that Democratic presidents use EOs more than Republican presidents[1]. What I don't know is whose EOs are "worse". I'd as soon Congress rip much of the EO power back out of the President's hands.
