ToTL--the plural of the word 'policy' is 'policies.' 
In English, the apostrophe is rarely used to form a plural noun. Most words ending with the letter 'y' are made plural by removing the 'y' and adding three letters--ies.
Good use of the 's to form the possessive in "your chosen party's plan" above. 
When you wrote that you and your fellow Republicans want "better opportunity for "all" of our citizens" you undercut the sincerity of your claim with the use of quotation marks. Since I don't think we can underline words for emphasis you could resort to all capital letters in order to emphasize a single word. Your writing seems a little less deplorable here than usual.
