Obviously, the Republican Party has no idea what being "fiscally responsible" actually means! A budget should include adequete revenue (i.e. taxes) to cover all the obligations. Republicans think the only way to balance a budget is to cut taxes. Democrats, like Bill Clinton, know that cutting expenses AND increasing revenue is the only way to balance a budget. Democrats' tax and spend idea is a lot more logical than the Republicans' borrow and spend policy!
Remember that about 75% of our national debt was caused by the last 3 Republican presidents! (Reagan, Bush41 and Bush43) The last two times the national budget was balanced a Democrat was president!! (Lyndon Johnson 1969 and Bill Clinton 2000)
