The correct answer is "posturing."
When a political group grandstands or exaggerate its position to the public, it can be said it is posturing for approval.
Political groups have much political and economic interest, so they always try to be in the public arena for posturing their issues. We can say that these groups always have a personal agenda with so many interests. That is why they lobby with legislators and men of power and influence. Many times, these groups tend to exaggerate on a specific situation in order to catch the public's attention. Other times, they magnify a situation for the people to believe it is very important to attend. So yes, when a political group grandstands or exaggerate its position to the public, it can be said it is posturing for approval.
