If you align the text to the right, you'll see where the problem is. The text on top of the centered text (your Constant Contact email form) is being positioned relatively, with a negative top value, to bring it up into the breadcrumb area. But positioning it relatively still reserves the space—for lack of a better term—so even though it's displayed out of the way it's still taking up space where it would normally be, preventing the text from being centered. Make sense?
<div style="float: right; position: relative; top: -27px; left: -30px;">
<div style="float: right; margin: -27px 0 0 -30px;">
…should fix it. Hope that helps…
