Main Menu Text Alignment

I am trying to arrange the text in the main menu, I need it to move up a bit from being centered as it is now, so that the bottom line on “Law Enforcement Agencies” isn’t hanging off in space.

I am sure what I want to change should be somewhere right in this bit of the CSS-

#mainmenu-container {
		height:66px;
		background:url(images/menu.png) left top no-repeat;
		padding:1px 44px;
		margin:0 -44px;
		position:relative;
		z-index:19;
	}

	#mainmenu li a {
		text-align:center;
		color:#4faec5;
		display:block;
		text-decoration:none;
		font-size:18px;
		font-family: 'overlock', sans-serif;
		padding:15px 25px;

	}
	#mainmenu a:hover{
		background:#48484a;

However, I’ve played with everything there that I thought would fix it (in my child CSS), and I’m still not getting it moved. If someone could point me in the right direction I would greatly appreciate it.
